Patent CA-2489263-A1 (CA)
Inventor: FRAZIER NINA CECILIA
IPC: D04H3/00
Filed: 2004-12-06
Abstract: The present invention provides an electret nonwoven web useable in a variety of applications. The nonwoven web is prepared from continuous fibers and once formed, a binder composition is applied to the nonwoven web. Generally the binder composition is sprayed on or impregnated into the nonwoven web and the binder composition is cured forming a nonwoven web/binder composite material. After the binder composition is cured, the composite is electret charged. The application of the binder composition to the nonwoven web provides the nonwoven web with stiffness and with characteristics such that it can be pleated and such pleats can be retained without the use of a supporting substrate. This makes the electret charged nonwoven web highly suitable and cost effective for filter media by eliminating the need for laminating the media to a supporting member.

Filed: 2004-12-10
Abstract: A method for the circulation of gas when drilling or working a well. The method includes the step of pressurizing at least two chambers of a multi-chambered accumulator with inert gas. The chambers of the multi-chambered accumulator are operatively connected to one another and individually or in combination isolatable from each other. The method also includes isolating at least one chamber of the accumulator that has been pressurized with inert gas such that during drilling or working the well the isolated chamber remains pressurized with gas that has not been mixed with well gas returns. Pressurized gas is extracted from one or more of the non-isolated chambers of the accumulator and injected into the well. At least a portion of the gas returns from the well is collected, compressed and delivered to at least one of the non-isolated chambers of the multi-chamber accumulator.

Title: Polyamino acids functionalized by at least one hydrophobic group and the therapeutic applications thereof
Inventor: ANGOT STEPHANIE
IPC: A61K47/48
Filed: 2003-07-23
Abstract: The invention relates to novel materials based on biodegradable polyamino acids that are useful for vectorizing active principle/s (AP). The aim of the invention is to supply a new polymeric raw material that is used for vectorizing AP and optimally fulfills all requirements concerning biocompatibility, biodegradability, the ability to be easily associated with numerous active principles or solubilize said active principles and to release the active principles in vivo. Said polymers can also be readily and economically transformed into particles vectorizing active principles according to the grafting rate of the hydrophobic groups, said particles being able to form stable aqueous colloidal suspensions. Said aim is achieved by the inventive amphiphile polyamino acids comprising aspartic and/or glutamic units that carry grafts which encompass at least one hydrophobic unit and are linked to the aspartic and/or glutamic units via a rotula containing two amide functions, more particularly via a spacer of the lysine or ornithine type. Said amide functions ensure better stability during hydrolysis than comparable products known in prior art. The invention also relates to new pharmaceutical, cosmetic, dietetic, or phytosanitary compositions based on the inventive polyamino acids.

Title: Composite impact assembly
Inventor: STRASSER DANIEL G
IPC: B60R19/02
Filed: 2005-02-01
Abstract: A bumper having an outer compressible layer, such as foam, positioned to absorb an impact and an inner layer of fiberglass laminated end-grain balsa for transferring residual load. The layers are wrapped in a fiberglass skin or urethane coating. The bumper is particularly useful when integrated into a frame used to mount fuel cylinders onto a vehicle roof. The bumper is attached to the frame using struts or balsa pillars and mounting plates so that loading resulting from an impact is transferred from the bumper and into the frame for preventing damage to the fuel cylinders. The mounting system can be configured to mount cylinders longitudinally in the direction of travel of the vehicle or transverse to the direction of travel. A bumper is attached at the front of the frame and a second bumper may be positioned at the back of the frame depending upon the configuration of the mounting.

Title: Method and apparatus for indicating activation of a smoke detector alarm
Inventor: ROBY RICHARD J
IPC: G08B1/08
Filed: 2003-10-02
Abstract: A method for detecting smoke detector alarms comprises analyzing at least two parameters of ambient sound over a period of time to detect a temporal pattern of the alarm. In one embodiment, a series of samples are taken over a period of time sufficiently long to include at least one full period of a repeating sound pattern, and the two parameters are frequency and amplitude of the loudest sound in each sample. The algorithmic analysis may be triggered by a detection algorithm that utilizes a lower amount of power than the algorithmic analysis. In other embodiments, the detection apparatus is incorporated into a conventional smoke detector (800) that will detect both smoke and an alarm from another detector. In another embodiment, a smoke detector (800) includes a transceiver (880) to transmit an activation signal to neighboring smoke detectors (890) when a fire is detected and to receive an activation signal from neighboring detectors (890).

Title: High performance transparent call distribution
Inventor: BURKE CHRISTOPHER J
IPC: G06F15/16
Filed: 2003-12-30
Abstract: A media server system includes a dispatcher and a set of processors either in the same physical system or in separate physical systems. The dispatcher receives the initial messages of respective session initiation dialogs from sources such as application servers. For each message, the dispatcher selects one of the processors to conduct the session initiation dialog and forwards the message to the selected processor using a port number uniquely associated with the processor and a switch fabric that routed the message to the processor associated with the modified port number. Upon receiving an initial session dialog message from the dispatcher, each processor creates a response message including the processor~s port identifier, and sends the response message to the application server that was the source of the initial message.  Subsequent messages of the session initiation dialog are sent directly to the selected processor by the application server, bypassing the dispatcher.

Title: Method for producing metallic iron
Inventor: KIKUCHI SHOICHI
IPC: C21B13/00
Filed: 2004-01-16
Abstract: A method for producing metallic iron wherein a mixture containing a carbonaceous reducing agent and iron oxides is supplied onto the hearth of a traveling reduction melting furnace and is heated to reduce and melt the iron oxide and the resultant metallic iron is cooled and then is discharged to the outside of the furnace and recovered, which comprises spreading, in advance, a hearth material having a powdery or granular form all over the hearth into a layer, to form a renewable hearth, prior to the supply of the raw material mixture, removing a part or all of the renewable hearth having been deteriorated in the operation of the furnace, supplying a new hearth material to renew the renewable hearth, leveling out the renewed hearth, and then supplying the above mixture to produce metallic iron. The method allows the easy removal and restoration even when a powder of metallic iron is buried in the surface of the hearth or the hearth is infiltrated or eroded by a slag, which results in the improvement of the availability and the easiness in the maintenance of a hearth and leads to the continuous operation of the hearth for a long period.
